US-2004-0020131 and/orUS-2008-0127563, which are all hereby incorporated herein by referencein their entireties.

Optionally, the window assembly or assemblies of the present inventionmay utilize aspects of the window assemblies described in U.S. Pat. Nos.8,402,695; 7,073,293; 7,003,916 and/or 6,691,464, and/or U.S.Publication Nos. US-2006-0107600; US-2008-0127563; US-2004-0020131and/or US-2003-0213179, which are hereby incorporated herein byreference in their entireties. Optionally, the fixed window panels andmovable window panel may include one or more electrically conductiveelements, such as heater grids or the like, which may be poweredutilizing aspects of the window assemblies described in U.S. Pat. No.8,402,695, which is hereby incorporated herein by reference in itsentirety. Although shown and described as a horizontally movable centerwindow that moves relative to a pair of opposite side windows (such asfor applications at the rear of a cab of a pickup truck or the like), itis envisioned that the present invention is applicable to other types ofmovable window assemblies, such as horizontally movable window panelsthat move relative to a single fixed window panel and/or frames (such asfor a rear or side opening of a vehicle or the like), and/or such asvertically movable window panels that move relative to one or more fixedpanels and/or frames (such as for a rear or side opening of a vehicle orthe like), while remaining within the spirit and scope of the presentinvention.

As shown in FIGS. 12-17, a rear slider window assembly may typicallyinclude a lower channel portion 14″ and an upper channel portion 15″bonded to an inner surface of a fixed window panel 16″. The channelportions 14″, 15″ may comprise plastic molded channel portions and mayreceive respective metallic guide elements 14 a″, 15 a″ disposed thereinfor receiving a lower carrier 22″ (FIG. 12) adhered along a lower edgeregion of the movable window panel 20″ (such as via an adhesive 23″disposed within a channel of carrier 22″ that receives the lower edge ofthe movable window panel 20″). The catch or latching element 24″ may bebonded at an inner surface of the fixed panel 16″ for latching orlocking the movable window panel 20″ in its closed position (FIG. 13).The channel portions are molded or formed with the guide elementsdisposed therein, and require adhering or insert molding or the like toform the channel or frame portions and to adhere or bond the channel orframe portions and the carrier portion and the latching element to therespective glass window panels.

In accordance with the present invention, the rear slider windowassembly includes channel portions 14, 15 that are formed or molded outof a plastic or polymeric or polycarbonate or acrylic material and thatobviate the need for the additional guides or channel elements receivedin and along the channels for engaging the movable window panel and/orcarrier as it moves relative to the channel portions and fixed windowpanels. For example, the rails or channel portions may be molded orformed with the fixed window panel or panels via a common molding orforming operation, such as injection molding of the channel portions andfixed window panel or panels (and optionally the latching element) in asingle mold and/or such as a single shot molding operation or amulti-shot or dual shot molding operation in a single mold (with themulti-shot molding operations optionally providing different colors,such as a clear or transparent panel or panels and colored or darkenedchannels and latch or the like). The operator thus may, after themolding process is completed and the material is cured or hardened,remove the unitarily formed channel portions, latching element and fixedwindow panel/panels from the mold, with no further processes (butoptionally the unitary construction or panel portion of the unitaryconstruction may be hard-coated or the like) or adhesives and/or thelike required to complete the channel/latch/panel construction.Likewise, for example, the carrier may be molded or formed with themovable window panel via a common molding or forming operation, such asinjection molding of the carrier and movable window panel in a singlemold and/or such as a single shot molding operation or a multi-shot ordual shot molding operation in a single mold (with the multi-shotmolding operations optionally providing different colors, such as aclear or transparent panel and a colored or darkened carrier or thelike). The operator thus may, after the molding process is completed andthe material is cured or hardened, remove the unitarily formed carrierand movable window panel from the mold, with no further processes (butoptionally the unitary construction or panel portion of the unitaryconstruction may be hard-coated or the like) or adhesives and/or thelike required to complete the carrier/panel construction.

As shown in FIG. 4, movable window 20 includes carrier 22 integrallyformed or molded with the panel portion 20 a of movable window 20 andalong the lower edge region 20 b of panel portion 20 a.

Optionally, and as shown in FIG. 5, fixed window 16 may include a catchor latching element 24 integrally formed therewith at an inboard edgeregion 16 c of the panel portion 16 a of fixed window 16. The panelportion 16 a and latching element 24 of fixed window 16 may be molded orotherwise integrally formed together out of any suitable material, suchas polycarbonate or the like, or such as an acrylic material or othermaterial that may be sufficiently transparent and durable. The panelportion 16 a of fixed window 16 may be coated with an anti-scratchcoating or the like to enhance the durability and scratch resistance ofthe window panel. Optionally, the latching element 24 may be colored ordarkened, such as via molding the latching element portion of the panelconstruction in a different color while molding the panel portion 16 ato be transparent or translucent or the like (such as via a dual shotmolding operation of the latching element and panel in a single mold.Optionally, the latching element and panel portion may be unitarilymolded or formed of a transparent material, and the latching elementmay, after molding and curing, be painted or coated with a colored ordark coating or ink or the like to provide the desired appearance.Optionally, the molded and cured unitary construction or at least thepanel portion of the unitary construction may be hard-coated forabrasion resistance, UV resistance and/or the like, such as by utilizingcoatings and the like as known in the transparent polymeric window art.As also shown in FIG. 5, the window panel 16 a may include a sliding orwiping seal 26 disposed vertically along the inboard edge region 16 c ofthe window panel 16 a for sliding or wiping engagement with the edgeregion 20 c of movable window panel 20 a as the movable window panel ismoved to its closed position and engages latching element 24 of fixedwindow 16.

With reference to FIG. 6, the lower channel portion 14 comprises aunitarily formed construction, with a receiving channel 14 a thatslidably receives carrier portion 22 of movable window 20 therein. Awiping seal 28 is disposed in or received in another channel 14 b of thechannel portion 14 for sliding or wiping engagement with the surface ofthe lower edge region 20 b of movable window panel 20 a as the movablewindow panel moves along the channel portion between its opened andclosed positions. The channel portion 14 includes an attaching surface14 c for attaching (such as via adhering or bonding) the channel portionto the vehicle frame or sheet metal when the window assembly 10 isinstalled in the vehicle. The channel portion 14 provides asubstantially continuous outer surface 14 d and may be colored ordarkened to provide the desired appearance and to render covert the seal28 and carrier portion 22 to a person viewing the window assembly fromthe outside of the vehicle.

Similarly, and with reference to FIG. 7, the upper channel portion 15comprises a unitarily formed construction, with a channel 15 a thatreceives a guide element 30 that slidably receives an upper edge region20 d of movable window panel 20 a therein. A wiping seal 32 is disposedin or received in another channel 15 b of the channel portion 15 forsliding or wiping engagement with the movable window panel 20 a as themovable window panel moves along the channel portion between its openedand closed positions. The channel portion 15 includes an attachingsurface 15 c for attaching (such as via adhering or bonding) the channelportion to the vehicle frame or sheet metal when the window assembly 10is installed in the vehicle. The channel portion 15 provides asubstantially continuous outer surface 15 d and may be colored ordarkened to provide the desired appearance and to render covert theattaching portion of the seal 32 and the guide element 30 to a personviewing the window assembly from the outside of the vehicle.

Optionally, and desirably, and with reference to FIGS. 8 and 9, thelower channel 14 and the upper channel 15 may be integrally formed ormolded with fixed window panels 16 a, 18 a (FIGS. 8 and 9 show thechannel as formed with fixed window panel 18, and the channel may besimilarly unitarily formed with fixed window panel 16). The panelportions 16 a, 18 a of fixed windows 16, 18 may be molded as transparentor substantially transparent or translucent panels and may be coatedwith an anti-scratch coating or the like to enhance the durability andscratch resistance of the window panels. Optionally, the channelportions 14, 15 may be colored or darkened, such as via molding thechannel portions (and outer surfaces 14 d, 15 d) in a different color ordarkened color while molding the panel portions 16 a, 18 a to betransparent or translucent or the like (such as via molding the channelportions in a different color while molding the panel portions to betransparent or translucent or the like, such as via a dual shot moldingoperation of the channel portions and panel portions in a single mold).Optionally, the channel portion 14, 15 may be painted or coated with acolored or dark coating or ink or the like to provide the desiredappearance (such as via unitarily molding or forming the channelportions and panel portions of a transparent material, whereby thechannel portions may, after molding and curing, be painted or coatedwith a colored or dark coating or ink or the like to provide the desiredappearance). Optionally, the molded and cured unitary construction or atleast the panel portion of the unitary construction may be hard-coatedfor abrasion resistance, UV resistance and/or the like, such as byutilizing coatings and the like as known in the transparent polymericwindow art.

Thus, a unitary fixed window construction may comprise the opposite orspaced apart fixed window panels and the upper and lower frame orchannel portions, all integrally molded or formed together (andoptionally including the latch element formed with one of the fixedwindow panels), and with the panel portions being clear or transparentand the channel portions being colored or darkened. As can be seen withreference to FIGS. 8 and 9, the outer surfaces 16 d, 18 d of windowpanels 16 a, 18 a may be generally flush or continuously formed with theouter surfaces 14 d, 15 d of lower and upper channels 14, 15 to providea uniform appearance along the upper and lower perimeter regions of thefixed window panels. Similarly, the outer surfaces 14 d, 15 d of thechannels at the center region of the window assembly may be generallyflush with or continuously formed with the outer surfaces 14 d, 15 d ofthe channels at the side or fixed window panel regions to provide auniform and flush perimeter of the window assembly. Optionally, and withreference to FIGS. 10 and 11, the unitarily molded channel portions 14′,15′ may be formed separately from the fixed window panels (only windowpanel 18 a′ shown in FIGS. 10 and 11) and may be adhered or bonded tothe fixed window panels, such as via a bonding adhesive or the like.

Therefore, the present invention provides a polycarbonate slider windowassembly formed from all polycarbonate (or acrylic or other suitablematerial) panels and channels, instead of glass panels with bondedhorizontal channels. The panel portions may be transparent polycarbonatepanels while the channel portions and latching element may be darkenedor colored, such as by molding (preferably in one shot) those portionsin a darkened color, such as a gloss black color or the like with thepanel portions being clear or transparent and the previous glass portionin clear. Also, anti-scratch coatings may be applied to the surfaces ofthe polycarbonate panels to enhance their durability and scratchresistance. Although polycarbonate panels are typically more expensivethan glass window panels, the present invention may achieve cost savingsover conventional rear slider window assemblies by eliminating laborprocesses and assembly processes, such as the processes of priming theglass panels, applying adhesives, and/or fixturing the panels andchannel portions and latching elements and carriers, and/or the like.

Optionally, and with reference to FIGS. 18A-30, a slider window assembly110 for a vehicle may include a fixed window panel 116 and a movablewindow panel assembly 118 that is movable between an opened position(where the movable window panel assembly is disposed behind a portion ofthe fixed window panel 116) and a closed position (where the movablewindow panel is disposed at an opening 116 a of fixed window panel 116).In the illustrated embodiment, fixed window panel 116 is configured tobe adhered to a vehicle, such as to a recess in the vehicle body or tothe frame or sheet metal of a vehicle, such as via a bead of adhesiveand/or sealant disposed around a perimeter region of the inner surfaceof the fixed window panel that adheres and bonds and seals the fixedwindow panel at the vehicle body. The window assembly 110 includes alower rail or channel member 114 adhered or bonded to a lower region ofan inner surface of fixed window panel 116 and an upper rail or channelmember 115 adhered or bonded to an upper region of the inner surface offixed window panel 116. Lower rail 114 includes one or more (such as twoas shown in the drawings) water drains or holes established therethroughto allow water that may accumulate in the lower rail 114 to flow throughthe rail 114, as discussed below. The rails fixed at the fixed windowpanel cooperate with channel followers and pins of the movable window118 and function to guide the movable window along the rails and towardthe fixed window panel when the movable window is moved to its closedposition, as also discussed below. The movable window panel thus may bemovable along the rails between an opened position, where the movablewindow is disposed inward of the fixed window panel, and a closedposition, where the movable window is disposed at the opening in thefixed window panel and at least partially in the opening to provide agenerally flush or continuous exterior surface of the fixed and movablewindow panels when the movable window panel is closed.

At least one water management shroud or drainage receiving conduit 120(such as two drainage receiving conduits as shown in FIGS. 18A-21 and26) is disposed at and spaced from the water drain hole and the lowerrail 114 and is configured to receive water from the water drain hole ofthe lower rail and to guide the water along the fixed window panel 116and through the adhesive bead or seal 121 (FIGS. 21 and 21A-B) thatattaches the inner surface of the fixed window panel 116 to the vehicle,so that the water is guided or channeled out of the window assembly. Thebead of adhesive or sealant 121 is disposed between the fixed windowpanel and the vehicle body and has a thickness (such as a desiredthickness or bond-line thickness selected to achieve the desired bondingof the adhesive to the fixed window panel and to the vehicle body, suchas a thickness on the order of a few millimeters or more or less). Thefixed window panel is thus directly attached to the vehicle via the beadof sealant or adhesive 121, such as a bead of moisture-cured urethaneadhesive, which adheres or bonds the window panel to the vehicle andprovides a watertight seal and provides a spacer or cushioning functionbetween the fixed window panel and the vehicle body. Such an adhesivebead typically has a dimension or thickness of a few millimeters orthereabouts. As best shown in FIGS. 21 and 21A, the drainage receivingconduit 120 is bonded or attached to the inner surface 116 b of thefixed window panel 116 and extends through the bead of adhesive orsealant 121 to provide a channel or conduit through the bead of adhesiveor sealant to facilitate controlled flow of water through theadhesive/sealant and out from the window assembly.

Various water drainage techniques have been proposed for vehiclewindows. For example, EP Patent Publication No. EP 1 048 501 B1 (whichis hereby incorporated herein by reference in its entirety) discloses adevice for shutting a window of a vehicle, with a functional element orrail added onto the surface of a fixed assembly. The functional elementor rail includes at least one water passage or cannula integrally formedtherewith which permits flow of water towards the exterior of thevehicle. The water passages are cannulas or tubes extending on thesurface of the fixed assembly which faces towards the interior of thevehicle and pass through seals which are placed on the surface of thefixed assembly which faces towards the interior of the vehicle. Suchwater passages, which are formed as part of the functional element orrail of the window assembly, have disadvantages. For example, suchintegrally formed rails and water passages (where the water passage isformed with the rail via a common forming or molding process toestablish a unitary construction comprising the rail and waterpassageways) are inflexible for applications to different windowapplications with window panels of different sizes or lengths. Also, thelower rail, with the water passages integrally formed therewith, cannotbe used as a universal rail for other window applications and/or for anupper rail application on a particular window assembly (since such anapplication would have the integrally formed water passages protrudingupwardly from the upper rail).

With respect to the water management shrouds or drainage receivingconduits of the present invention, the drainage receiving conduits 120are separate from and spaced from and are not physically connected to orformed with the lower rail 114, and thus the lower rail may be readilyused in other applications and/or can be used as a universal rail forboth upper and lower rail applications. As best shown in FIGS. 20 and21, the drainage receiving conduits 120 are adhered or bonded to thefixed window panel 116 at locations below and spaced from the waterdrain holes 114 a of the lower rail 114 (and optionally a drainage holeextension 114 b of the lower rail 114 such as shown in FIGS. 21 and 21C)for receiving water that flows or drips from the water drain holes 114 aand/or drainage hole extension 114 b. The drainage receiving conduits120 are configured to guide or channel or conduit the received waterdownward along the fixed window panel and through the adhesive bead orseal 121 that attaches the fixed window panel to the vehicle, wherebythe water is discharged from the shrouds outside of the window assembly110.

As best shown in FIGS. 21, 21A and 21C, the water drainage receivingconduits 120 comprise a generally linear or straight (or other shapedepending on the particular application) conduiting or channeling orguiding portion 120 a and an enlarged upper receiving portion 120 b. Thereceiving portion 120 b is generally cup-shaped or funnel-shaped and isdisposed at the drain hole 114 a or drainage hole extension 114 b of thelower rail 114 so that water flowing or dripping through the drain hole114 a and drainage hole extension 114 b is received in the receivingportion 120 b of water drainage receiving conduit 120. Optionally, andpreferably, there need not be any physical contact or connection betweenthe drainage extension 114 b of the rail 114 and the receiving end 120 bof drainage receiving conduit 120 (such as shown). Optionally, thereceiving end 120 b of drainage receiving conduit 120 may partiallyreceive (yet not contact) the drainage extension 114 b of lower rail,such as shown in FIG. 21C. Optionally, and less desirably, the receivingend of the drainage receiving conduit may be connected to or formed withthe drainage extension and lower rail to provide a unitary rail anddrainage conduit construction. In such an application, the receivingportion need not be cup-shaped and would be formed in the same shape asand as part of the drainage extension of the lower rail, and thuscomprise an elongated drainage extension formed as part of the lowerrail.

As can be seen with reference to FIG. 21A, the water drainage receivingconduit 120 may comprise a semi-circular shape with its open sideattached or adhered or bonded to the inner surface of the fixed windowpanel 116. In the illustrated embodiment, water drainage receivingconduit 120 includes a pair of attachment flanges or wings 120 c thatprovide a bonding surface for adhering or taping or affixing the conduitto the window panel, with the inner surface of the window panel 116forming a wall or side of the conduit and with a passageway 120 festablished along the conduit and between the inner surface 116 b ofwindow panel 116 and the conduiting portion 120 a of drainage conduit120. Optionally, the flanges or wings 120 c may include bumps orprotrusions 120 d to establish the desired or appropriate bond-linethickness for an adhesive 120 e disposed between the flanges 120 c andthe window panel 116 (such as by utilizing aspects of the windowassemblies described in U.S. Pat. Nos. 5,551,197 and 5,853,895, whichare hereby incorporated herein by reference in their entireties). Asshown in FIG. 21A, the water drainage receiving conduit 120 is attachedto the inner surface of the fixed window panel 116, and theadhesive/sealant bead 121 is disposed around the perimeter of the fixedwindow panel 116 and over the conduiting portion 120 a of conduit 120,whereby the fixed window panel is adhered to the vehicle body 112.Optionally, the window panel 116 may have a darkened coating or darkfrit layer established around its perimeter to render covert the sealand/or conduits and/or upper and lower rails (or other means fordarkening the portion of the window panel at and around theseal/conduits/rails) to provide an enhanced aesthetic appearance to thewindow assembly when the window assembly is normally mounted or adheredto the vehicle.

Optionally, and as shown in FIG. 21B, a water drainage receiving conduit120′ may comprise a closed conduit, with its passageway 120 f′ providedwithin the conduiting portion 120 a′. An inner wall 120 c′ of conduit120′ provides the attaching surface for attaching or adhering or bondingthe conduit 120′ to the inner surface 116 b of the window panel 116.Optionally, the inner wall 120 c′ may include bumps or protrusions 120d′ to establish the desired or appropriate bond-line thickness for anadhesive 120 e′ disposed between the inner wall 120 c′ and the innersurface 116 b of window panel 116. Although shown and described ascomprising generally semicircular-shaped conduits and cup-shapedreceiving portions, clearly the water drainage conduits of the presentinvention may comprise any suitable shape and may extend generallystraight downward or at an angle or may be curved, while remainingwithin the spirit and scope of the present invention. As shown in FIG.21B, the water drainage receiving conduit 120′ is attached to the innersurface 116 b of the fixed window panel 116, and the adhesive/sealantbead 121 is disposed around the perimeter of the fixed window panel 116and over the conduiting portion 120 a′ of conduit 120′, whereby thefixed window panel is adhered to the vehicle body 112′.

Optionally, and with reference to FIGS. 22-24A, a water drainagereceiving conduits 120″ comprise a conduiting or channeling or guidingportion 120 a″ and an upper receiving portion 120 b″. The receivingportion 120 b″ is shaped to be larger than the drainage hole extension114 b″ of the lower rail 114″ and is disposed below the drainage holeextension 114 b″ of the lower rail 114″ so that water flowing ordripping through the drain hole and drainage hole extension 114 b″ isreceived in the receiving portion 120 b″ of water drainage receivingconduit 120″. As shown in FIG. 22, the receiving conduits 120″ may bespaced from and disposed below the drainage hole extensions 114 b″ sothat there is not any physical contact or connection between thedrainage extension 114 b″ of the rail 114″ and the receiving end 120 b″of drainage receiving conduit 120″. Optionally, and as shown in FIGS. 24and 24A, the receiving conduits 120″ may be disposed below the drainagehole extensions 114 b″ and may partially receive the extensions 114 b″with no physical contact or connection between the drainage extension114 b″ of the rail 114″ and the receiving end 120 b″ of drainagereceiving conduit 120″. Optionally, and as shown in FIGS. 18B and 24A,the conduiting portion 120 a″ may have baffles or guides 120 d″established therein to guide the water through the conduiting portion120 a″ to reduce or limit wind noise when the vehicle travels along aroad or highway or the like.

As can be seen with reference to FIGS. 23A and 23B, the water drainagereceiving conduit 120″ may comprise a semi-circular receiving shape withits open side attached or adhered or bonded to the inner surface of thefixed window panel 116″. In the illustrated embodiment, water drainagereceiving conduit 120″ includes a pair of attachment flanges or wings120 c″ that provide a bonding surface for adhering or taping or affixingthe conduit to the window panel, with the inner surface of the windowpanel 116″ forming a wall or side of the conduit and with a passageway120 f″ established along the conduit and between the inner surface 116b″ of window panel 116″ and the conduiting portion 120 a″ of drainageconduit 120″. Optionally, the flanges or wings may include bumps orprotrusions to establish the desired or appropriate bond-line thicknessfor an adhesive disposed between the flanges and the window panel (suchas by utilizing aspects of the window assemblies described in U.S. Pat.Nos. 5,551,197 and 5,853,895, which are hereby incorporated herein byreference in their entireties). The water draining receiving conduit120″ and drainage hole extension 114 b″ may be otherwise similar to thewater draining conduits and extensions discussed above.

Such a water shroud or water management configuration or drainagereceiving conduit has many advantages over the previously proposed waterpassages. For example, the water drainage receiving conduits of thepresent invention allow the window manufacturer to make or form the railand drainage receiving conduits out of different materials, such as byusing a higher cost, more rigid engineering plastic or the like for therail and a lower cost, optionally less rigid material (such as apolypropylene or the like) for the drainage receiving conduits (which donot have to support and guide the movable window panel like the lowerrail does). Also, the water shroud or drainage receiving conduitconfiguration of the present invention allows for a universal rail forapplication to different windows of different lengths or widths, andallows for use of the lower rail as an upper rail as well. Thus, thepresent invention provides flexibility to the manufacturer to make anduse universal or common rails for upper and lower applications and/orfor different window applications.

As best shown in FIG. 20, the upper rail 115, lower rail 114 and waterdrainage receiving conduits 120 are adhered to the interior surface ofthe fixed window panel 116. For example, the rails may be bonded to thefixed glass panel using any suitable adhesive, such as a one componenturethane adhesive, such as a moisture cured adhesive, such as BETASEAL™or the like, while the water management shrouds or drainage receivingconduits 120 may also be bonded to the fixed glass panel using anysuitable adhesive, such as a one component urethane adhesive, such as amoisture cured adhesive, such as BETASEAL™ or the like. Likewise, a pairof locating clips 122 may be bonded at an upper region of the fixedglass panel using any suitable adhesive, such as a one componenturethane adhesive, such as a moisture cured adhesive, such as BETASEAL™or the like. A pair of spacers 124 may be attached or adhered to a lowerregion of the fixed glass panel, such as via any suitable adhesive, suchas via a double-sided tape or the like, and a seal 126 may be adhered orbonded at the opening 116 a of the fixed window panel 116 via anysuitable adhesive, such as via a double-sided tape or the like. A railcover 128 a may be mechanically attached to the lower rail 114 and arail cover 128 b may be mechanically attached to the upper rail 115,such as via snap elements or the like integrated into or formed with therail covers 128 a, 128 b and/or the rails 114, 115.

As shown in FIG. 25, the movable window assembly 118 includes a windowpanel 118 a, such as a glass window panel or polycarbonate window panelor the like, which is bonded to a frame portion 118 b, such as via anysuitable adhesive, such as a moisture cured adhesive, such as BETASEAL™or the like. A pair of channel followers 130 are disposed at the upperand lower end regions of the frame portion 118 b, and are biasedoutwardly away from the frame portion 118 b via respective biasingelements or springs 132. Likewise, a pair of pins 134 are disposed atthe upper and lower opposite end regions of the frame portion 118 b, andare biased outwardly away from the frame portion 118 b via respectivebiasing elements or springs 136. The channel followers 130 and pins 134guide the movable window assembly 118 along the upper and lower rails115, 114. The pin springs 132, 136 are inserted into the pins 134 andthe channel followers 130, which are then inserted into mating holes onthe frame portion 118 b. The springs 132, 136 at all four corners of theframe portion 118 b function to “float” the movable window assemblybetween the rails, thus centering the movable window assembly or moduleand reducing chucking movement when operating or opening/closing themovable window.

In the illustrated embodiment, the movable window assembly or module 118includes a latching mechanism 138 that secures the movable windowrelative to the fixed rails and fixed window panel via insertion ofdetent pins 138 a into apertures of the fixed rails 114, 115. In theillustrated embodiment, latching mechanism 138 includes the detent pins138 a, which are mounted at an end of the movable window frame portion118 b and which are biased outwardly (towards the respective rails) viaa detent pin spring 138 b. Latch buttons 138 c are disposed at thedetent pins 138 a and spring 138 b and, when squeezed by an operator oruser of the window, function to pull the detent pins inward to disengagethem from the rails to allow for sliding movement of the movable window118 along the rails 114, 115 and fixed window panel 116. A biasingelement or spring 138 d (such as a leaf spring or torsional spring orthe like) is disposed at latch buttons 138 c to bias or hold the latchbuttons outward, keeping the latch buttons from rattling when themovable window is in an open position between detent locking holes. Aframe cover 140 may be mechanically attached, such as by snaps or thelike, to the frame portion 118 b. The springs 138 d may be attached tothe latch buttons 138 c (such as shown in FIG. 28) or may be attached tothe frame cover 140, such as via mechanically using barbs or springinterference to a rib on the cover. Thus, the detent pins 138 a areguided into the frame through frame holes, and are separated andactuated by the detent pin spring 138 b, which is held into place by thelatch buttons 138 c, which are mechanically attached though snaps or thelike onto the frame 118 b. As best seen in FIG. 29, when the movablewindow is closed, the channel followers 130 are driven in towards thefixed glass panel 116, providing a means of securing the non-latchedportion of the movable window to reduce or substantially preclude forcedentry.

Thus, the present invention provides a movable slider window assemblywith a movable window that is moved along rails between an opened andclosed position relative to a fixed window panel and aperture or openingformed through the fixed window panel (such as by utilizing aspects ofthe window assemblies described in U.S. Pat. Nos. 8,322,073; 8,048,529;7,838,115; 7,332,225; 6,846,039; 6,319,344; 6,068,719 and 5,853,895,which are all hereby incorporated herein by reference in theirentireties). The fixed window panel is adhered or bonded to the vehiclebody and the window assembly includes separate water drainage receivingconduits for channeling or guiding water draining from the lower railthrough the adhesive or sealant bead between the fixed window panel andthe vehicle body to drain water from the window assembly. The rails andchannel followers and pins function to guide the movable window alongthe rails and toward the fixed window panel when the movable window ismoved to its closed position. The movable window panel thus is movablealong the rails and moves between an opened position, where the movablewindow is disposed inward of the fixed window panel, and a closedposition, where the movable window is disposed at the opening in thefixed window panel and at least partially in the opening to provide agenerally flush or continuous exterior surface of the fixed and movablewindow panels when the movable window panel is closed.

Referring now to FIGS. 31 and 32, a rear slider window assembly 210 of avehicle 212 (such as a pickup truck or the like) includes a window frame214, a pair of side fixed window panels 216, 218 and a movable windowpanel 220 that is movable relative to frame 214 and fixed window panels216, 218 between an opened position and a closed position. Fixed windowpanels 216, 218 each include an electrically conductive heater grid 222,223 or other heating element or electrically operable elementestablished at the window panels (such as at or on an interior surfaceof the window panels) and movable window panel 220 includes anelectrically conductive heater grid or other heating element orelectrically operable element 224 established at the window panel (suchas at or on an interior surface of the movable window panel). The heatergrids 222, 223 are electrically conductively connected to (or areotherwise in electrical conductive continuity with) a power source ofthe vehicle and may be powered (such as responsive to a user actuatableinput or switch or button of the vehicle or responsive to a sensor oraccessory of the vehicle) to heat or defrost or defog the fixed windowpanels 216, 218. Movable panel heater grid 224 is electrically connectedto the power source (and may be electrically connected to electricalterminals or elements at one of the heater grids 222, 223 of the fixedwindow panels) and may be electrically powered to heat or defrost ordefog the movable window panel 220, as discussed below. Heater grids222, 223, 224 comprise a plurality of electrically conductive tracesthat extend across the respective window panels 216, 218, 220 betweenrespective busbars to provide enhanced and more uniform heating anddefrosting/defogging of the window panel, as also discussed below.

Heater grid 224 of movable window panel 220 is powered in a manner thatallows for heating or defogging or defrosting of the movable windowpanel irrespective of whether the movable window panel is opened orpartially opened or closed, as discussed below. In the illustratedembodiments, the electrical connection between the vehicle power sourceor fixed panel heater grid 222 is electrically connected to movablepanel heater grid 224 via a flexible connector or wire or cable 226, andfixed panel heater grid 222 is electrically connected to fixed panelheater grid 223 via a jumper wire or cable 228, such as discussed below,and such as by utilizing aspects of the rear slider window assembliesdescribed in U.S. Pat. No. 8,402,695, which is hereby incorporatedherein by reference in its entirety. Optionally, the heater grid 224 ofmovable window panel 220 may be powered only when in its closed positionand/or via any suitable powering means.

In the illustrated embodiment, window assembly 210 includes two fixedwindow panels 216, 218 that are spaced apart so as to define an openingtherebetween. Slider or movable window panel 220 is movable along lowerrail 214 a and upper rail 214 b of frame portion 214 to open and closethe opening, such as in a manner similar to known slider windowassemblies. Optionally, the slider window panel 220 may be disposed at alower carrier that receives the lower perimeter edge region of theslider window panel 220 therein and that is slidably or movably receivedin the lower rail 214 a of frame portion 214.

Optionally, the window assembly or assemblies of the present inventionmay utilize aspects of the window assemblies described in U.S. Pat. Nos.8,402,695; 7,073,293; 7,003,916 and/or 6,691,464, and/or U.S.Publication Nos. US-2006-0107600; US-2008-0127563; US-2004-0020131and/or US-2003-0213179 and/or U.S. provisional application Ser. No.61/426,065, filed Dec. 22, 2010, which are all hereby incorporatedherein by reference in their entireties.

The movable or slider window panel 220 may be movable such as via manualpushing or pulling at the window panel or in response to actuation of adrive motor of a drive motor assembly or system, which may move cablesor the like to impart horizontal movement of the slider window panel 220along the rails 214 a, 214 b, such as in a known manner. Optionally, thedrive motor assembly may utilize aspects of the drive assemblies of thetypes described in U.S. Pat. Nos. 4,920,698; 4,995,195; 5,146,712;5,531,046; 5,572,376; 6,119, 401; 6,955,009 and/or 7,073,293, and/orU.S. Publication Nos. US-2004-0020131 and/or 2008-0127563, which are allhereby incorporated herein by reference in their entireties.

Heater grids 222, 223, 224 may comprise any suitable electricallyconductive grids or coatings or layers established at the respectivewindow panels. For example, the electrically conductive heater grids maycomprise electrically conductive traces, such as electrically conductivesilver flakes that are mixed with low melting glass and applied orscreened as a thick film to a surface of the glass sheet for the windowor to a ceramic frit layer on the surface of the glass sheet and thenfired at a high temperature, such as in a known manner. The conductivematerial is established in a desired or appropriate pattern at thewindow panels, and a pair of terminals are established for electricallyconnecting a power source to the grid.

Although referred to herein as heater grids, clearly other types oftraces or patterns or coatings or layers or elements may be disposed atthe surface of the window panels, such as to heat the window panels whenpowered (or as discussed above, other electrical content may also orotherwise be established at the movable window panel and electricallyconnected to the vehicle power source and/or control depending on theparticular application and desired or selected electrical content of therear slider window assembly), while remaining within the spirit andscope of the present invention. For example, a conductive coating, suchas a transparent conductive coating or the like, may be disposed at thesurface of the window panels and may be heated when power is appliedthereto (such as when power is applied to conductive traces or busbarsthat are electrically conductively connected to opposite regions of thetransparent conductive coating).

In the illustrated embodiment, terminals 232, 233 at heater grids 222,223, respectively are established at a perimeter region of each of thefixed window panels (such as the lower outer corner region of the fixedwindow panels and such as at a frit-coated perimeter region of thewindow panel), and the terminals 232, 233 (such as spade terminals orthe like) are configured to electrically connect to connectors of avehicle wire harness (not shown) or the like. For example, a power orhot or positive wire of the vehicle wiring may connect to terminal 232at heater grid 222 of fixed window panel 216 and a ground or common wireof the vehicle wiring may connect to terminal 233 at heater grid 223 offixed window panel 218 (or optionally both the positive and negativefeeds of the vehicle wiring may connect to respective terminals at oneof the heater grids 222, 223, while remaining within the spirit andscope of the present invention).

In the illustrated embodiment, electrical connection of the vehiclepower source to heater grid 224 of movable window panel 220 is achievedvia flexible cable or wiring 226. In the illustrated embodiment,electrical connection between the heater grid 224 of the movable windowpanel and the power source of the vehicle is established via flexiblecable or wire 226 that is routed along the lower region of fixed windowpanel 216 and that is extendable or flexed as the movable window ismoved towards its closed position and is retractable or flexed as themovable window is moved towards its opened position, such as discussedin greater detail below. For example, one end of the flexible cable 226may connect to a pair of terminals or busbars at the fixed window panel218 (where the terminals may be electrically conductively connected tobusbars or terminals 222 a, 222 b of the heater grid 222 of fixed windowpanel 216, such as via respective metallic or otherwise electricallyconductive traces established at the surface of the fixed window paneland between the respective terminals), while the other end of flexiblecable 226 may connect to a pair of terminals or busbars 224 a, 224 b atmovable window panel 220 (where the terminals are electricallyconductively connected to or established with the heater grid 224 ofmovable window panel 220).

The heater grids 222, 223 of the fixed window panels 216, 218 areelectrically conductively connected to (or are otherwise in electricalconductive continuity with) a power source of the vehicle and may bepowered (such as responsive to a user actuatable input or switch orbutton of the vehicle) to heat or defrost or defog the fixed windowpanels 216, 218, while the heater grid 224 of movable window panel 220is electrically connected to the power source via electrical connectionto electrical terminals or elements at one of the heater grids of thefixed window panels (such as via flexible cable 226), and may beelectrically powered to heat or defrost or defog the movable windowpanel 220 in a manner that allows for heating or defogging or defrostingof the movable window panel irrespective of whether the movable windowpanel is opened or partially opened or closed, such as in a similarmanner as discussed above.

In the illustrated embodiment, heater grid 222 of fixed window panel 216includes terminal or electrical connector 232 for connecting to a powerfeed (such as a positive or negative feed) of the vehicle, while heatergrid 223 of fixed window panel 218 includes terminal or electricalconnector 233 for connecting to another power feed (such as a negativeor positive feed) of the vehicle, with the terminals 232, 233 beingdisposed at or near opposite perimeter regions or sides of the windowassembly. Such an electrical connection to the vehicle power source mayoccur for applications where the vehicle may optionally have either aconventional fixed window without a center slider panel of a rear sliderwindow assembly such as shown in FIG. 32. Window assembly 210 includes ajumper wire or cable or element 228 that established electricallyconductive connection between the heater grids 222, 223 of fixed windowpanels 216, 218.

In the illustrated embodiment, jumper element 228 comprises a pair ofwires 228 a, 228 b connected between opposite end connectors 236, 238.Jumper element 232 extends along the lower channel 214 b of frame 214,with connector 236 attached or disposed at fixed window panel 216 andconnector 238 attached or disposed at fixed window panel 218. As can beseen in FIG. 33, an end of one of the wire 228 a at connector 236 (notshown in FIG. 33) may be electrically connected to an electricallyconductive trace or busbar or terminal 222 a of heater grid 222 (thatmay extend from or be near to or be electrically conductively connectedto terminal 232 for connecting to the vehicle wiring harness when thewindow assembly is installed at a vehicle), while an end of the otherwire 228 b at connector 236 (not shown in FIG. 33) may be electricallyconnected to an electrically conductive trace or terminal 222 b ofheater grid 222 (that is at an opposite end or busbar of the heater gridor trace from the busbar 222 a, as discussed below). Likewise, theopposite end of wire 228 b at connector 238 is electrically connected toan electrically conductive trace or terminal 223 a of heater grid 223(that may extend from or be near to or be electrically conductivelyconnected to terminal 233 for connecting to the vehicle wiring harnesswhen the window assembly is installed at a vehicle), while the oppositeend of the other wire 228 a at connector 238 may be electricallyconnected to an electrically conductive trace or terminal 223 b ofheater grid 223 (that is at an opposite end or busbar of the heater gridor trace from the terminal or busbar 223 a, as discussed below).

Thus, the jumper wire or element 228 provides electrical connectionbetween a terminal of a heater grid at one of the fixed window panels(such as, for example, a positive terminal or busbar 222 a at heatergrid 222 at fixed window panel 216) and a terminal of a heater grid atthe other of the fixed window panels (such as, for example, a negativeterminal or busbar 223 a at heater grid 223 at fixed window panel 218).Thus, each heater grid 222, 224 of fixed window panels 216, 218 ispowered by electrical connection of a positive feed at a terminal on oneside of the window assembly and a negative feed at a terminal on theother side of the window assembly. The rear slider window assembly thusmay be mounted at a vehicle that has an electrical connection atopposite sides of the window assembly, such as may be provided for asingle fixed panel window assembly.

Although shown and described as having a positive terminal at one fixedpanel and a negative terminal at the other fixed panel and a jumper wireconnecting between the heater grids of the fixed panels, it isenvisioned that a jumper wire may be provided between heater grids of awindow assembly that has both the positive and negative terminalsestablished at one of the fixed window panels, with the jumper wireestablishing electrically conductive connection or continuity betweenthe heater grid with the terminals and the heater grid of the otherfixed window panel (via electrically connecting to respective traces atthe other fixed window panel), while remaining within the spirit andscope of the present invention. Likewise, although shown and describedas having the jumper wire extend along the lower channel of the windowassembly, clearly the jumper wire or element may be established at andalong the upper channel of the window assembly or may be established inand along the upper or lower channel, or one wire or element may beestablished at or in and along the upper channel and another wire orelement may be established at or in and along the lower channel, whileremaining within the spirit and scope of the present invention. Althoughshown and described as having a flexible cable for establishingelectrical connection between the heater grid of the movable windowpanel and the power source of the vehicle, it is envisioned that windowassembly may include any other suitable means for establishingelectrical connection between the heater grid of the movable windowpanel and the power source of the vehicle in a manner that allows forheating or defogging or defrosting of the movable window panel (orotherwise provides electrical power to an electrical element of themovable window panel) irrespective of whether the movable window panelis opened or partially opened or closed, such as via any of the optionalmeans described herein.

The heater grids 222, 223, 224 of window assembly 210 provide forenhanced performance and more uniform heating via the routing of theheater traces and arrangement of the heater busbars at each of therespective window panels 216, 218, 220. In the illustrated embodiment ofFIGS. 32 and 33, the heater grids 222, 223, 224 comprise one or moreelectrically conductive traces or busbars extending vertically along oneperimeter side or region of the respective window panel 216, 218, 220and two or more separate electrically conductive traces or busbars atthe opposite perimeter side or region, with generally horizontalelectrically conductive traces extending between and electricallyconductively connecting the generally vertical traces or busbars. Thisconfiguration allows for the flow of electrical current along some ofthe heater traces to flow across the respective window panel in onedirection and the flow of electrical current along others of the heatertraces to flow across the respective window panel in the oppositedirection, and results in more uniform heating of the heater traces toprovide enhanced defogging or defrosting of the respective window panelduring operation of the heater grids. The heater grids 222, 223, 224 ofthe window assemblies shown in FIGS. 32 and 33 are substantially similarin configuration and will not be separately discussed herein, with theterminals and lower busbars of the grids being configured differentlyfor electrical connection to the jumper wires, flexible connectors andvehicle wiring harnesses of the particular applications of the windowassemblies.

For example, and as can be seen in FIGS. 32 and 33, heater grid 222 offixed window panel 216 has an input or positive feed electricallyconductive trace or busbar 222 a along its outer or outboard perimeterside or region (with positive feed busbar 222 a extending downward belowthe horizontal traces or grids for jumper wire 228 a to electricallyconnect to and for a lead of flexible cable 226 to electrically connectto), with a plurality of generally horizontal traces 222 c extendingfrom positive feed busbar 222 a across fixed window panel 216 to aninboard busbar 222 d that extends generally vertically along the inboardperimeter side or region of fixed window panel 216. A plurality ofgenerally horizontal traces 222 e extend from inboard busbar 222 d andback across fixed window panel 216 to a second busbar 222 b at outboardperimeter side or region of fixed window panel 216. In the illustratedembodiment, the positive feed busbar 222 a is disposed along theoutboard perimeter side or region of fixed window panel 216 with traces222 c extending across an upper region of fixed window panel, and thesecond busbar 222 b is disposed along a lower perimeter outboard sideregion of fixed window panel 216 with traces 222 e extending across alower region of fixed window panel (with the second busbar 222 bextending downward to establish the terminal or conductive trace forconnection to the flexible connector 226 and the jumper cable 228). Thejumper wires 228 a, 228 b, at connector 236, electrically connect topositive busbar 222 a and to the second outboard or negative busbar 222b.

Similar to fixed window 216, fixed window panel 218 has a feed or inputor positive electrically conductive trace or busbar 223 b (to whichjumper wire 228 a, at connector 238 (not shown in FIG. 33), iselectrically connected) and a second outboard or negative or groundelectrically conductive trace or busbar 223 a (at which terminal 233 isdisposed and to which jumper wire 228 b, at connector 238, iselectrically connected), with a plurality of generally horizontal traces223 c extending from positive feed busbar 223 b across fixed windowpanel 218 to an inboard busbar 223 d that extends generally verticallyalong the inboard perimeter side or region of fixed window panel 218. Aplurality of generally horizontal traces 223 e extend from inboardbusbar 223 d and back across fixed window panel 218 to second outboardbusbar 223 a at the outboard perimeter side or region of fixed windowpanel 218. In the illustrated embodiment, the positive feed busbar 223 bis disposed along the outboard perimeter side or region of fixed windowpanel 218 with traces 223 c extending across an upper region of fixedwindow panel, and the second or negative busbar 223 a is disposed alonga lower perimeter outboard side region of fixed window panel 218 withtraces 223 e extending across a lower region of fixed window panel andwith busbar 223 a providing for terminal 233 and extending downward toestablish a connection to jumper wire 228 b at connector 238.

Similarly, heater grid 224 of movable window panel 220 comprises apositive feed electrically conductive trace or busbar 224 a and anegative electrically conductive trace or busbar 224 b, to which the endof flexible cable 226 is electrically connected, with one wire 228 a offlexible cable 226 electrically connecting busbar 222 a of fixed windowpanel 216 to busbar 224 a of movable window panel 220 and another wire228 b of flexible cable 226 electrically connecting a busbar terminal ofbusbar 222 b of fixed window panel 216 to busbar terminal or trace 224 bof movable window panel 220. Heater grid 224 of movable window panel 220includes a plurality of generally horizontal traces 224 c (such as threetraces) extending from a generally vertical portion of positive feedbusbar 224 a across movable window panel 220 to an opposite side busbar224 d that extends generally vertically along the opposite perimeterside or region of movable window panel 220. A plurality of generallyhorizontal traces 224 e (such as three traces) extend from busbar 224 dand back across movable window panel 220 to a second generally verticalbusbar 224 f at the first perimeter side or region of movable windowpanel 224 (with the conductive trace or busbar 224 f being disposedgenerally parallel to and inboard of the generally vertical portion ofbusbar 224 a). Further, in the illustrated embodiment, a plurality ofgenerally horizontal traces 224 g (such as three traces) extend frombusbar 224 f across movable window panel 220 to a generally verticalportion of busbar 224 b. In the illustrated embodiment, the positivefeed busbar 224 a extends generally horizontally along a lower region ofmovable window panel 220 and extends generally vertically and at leastpartially along the opposite perimeter side of movable window panel 220,with one of the wires of the flexible cable 226 electrically connectingto the busbar terminal at the end of the horizontal portion of busbar224 a. The positive feed busbar 224 a thus is disposed generallyvertically along a trailing perimeter side or region of movable windowpanel 220 (the side that trails the window panel as the movable windowpanel is moved towards its opened position) with traces 224 c extendingacross an upper region of fixed window panel, and the second busbar 224d is disposed along an opposite upper perimeter side region (the leadingedge that leads the window panel as the movable window panel is movedtowards its opened position) of movable window panel 220 with traces 224e extending back across a middle region of movable window panel, and thebusbar 224 f is disposed along the lower side region of the first ortrailing side of the window panel with traces 224 g extending across alower region of the movable window panel to the busbar 224 b disposedalong the second or leading perimeter edge region of the movable windowpanel, and with the busbar 224 b extending downward to provide aterminal or connection at a lower or bottom region of movable windowpanel 220 for connection to one of the wires of the flexible connector226.

Thus, the heater grid configuration of the rear slider window assemblyof the present invention allows for current flow across the windowpanels between at least one busbar on one side of each window panel andat least two busbars on the opposite side of each window panel. Thecurrent flow on each window panel thus may flow along an input or feedbusbar and across the window panel to another busbar and then backacross the window panel to a third busbar that is generally at or nearor adjacent to the first or input or feed busbar. Thus, each heater gridof the respective window panel provides enhanced current flow across therespective window panel and a more uniform or even defogging ordefrosting pattern and allows for narrower generally vertical busbarsalong each side of the window panel.

Referring now to FIGS. 34-41, a rear slider window assembly 210′includes fixed window panels 216′, 218′ and a movable window panel 220′,with heater grids 222′, 223′, 224′ established thereat, such as in asimilar manner as discussed above. The heater grids 222′, 223′, 224′ andjumper wire or cable 228′ of window assembly 210′ are substantiallysimilar to the heater grids 222, 223, 224 and jumper wire or cable 228of window assembly 210, discussed above, such that a detailed discussionof the heater grids and jumper wires need not be repeated herein. Thesimilar or common elements of the heater grids and jumper wires arereferenced in FIGS. 34-41 with similar reference numbers as used inFIGS. 32 and 33.

In the illustrated embodiment, window assembly 210′ includes a flexibleconnector 226′ that comprises a pair of flat wires 236′, 237′ that flexin one direction (such as in a horizontal direction in FIGS. 36-41),while limiting flexing in the other direction (such as in a verticaldirection in FIGS. 36-41). In the illustrated embodiment, one end 236a′, 237 a′ of the wires 236′, 237′ of flexible cable 226′ are connectedto a pair of terminals or busbars 222 a′, 222 b′ at the fixed windowpanel 216′ (where the ends 236 a′, 237 a′ of the wires 236′, 237′ may beelectrically conductively connected to busbars or terminals 222 a′, 222b′, respectively, of the heater grid 222′ of fixed window panel 216′,such as via respective metallic or otherwise electrically conductivetraces established at the surface of the fixed window panel and betweenthe respective terminals), while the other end 236 b′, 237 b′ of wires236′, 237′ of flexible cable 226′ may connect to a pair of terminals orbusbars 224 a′, 224 b′, respectively, at movable window panel 220′(where the terminals are electrically conductively connected to orestablished with the heater grid 224′ of movable window panel 220′, suchas discussed above).

As shown in FIG. 37, ends 236 b′, 237 b′ of wires 236′, 237′ may beelectrically connected at terminals 224 a′, 224 b′ of heater element224′ of movable window panel 220′ (such as via any suitable electricalconnection means, such as via having the ends 236 b′, 237 b′ received inand crimped or clamped via electrical connectors or elements 238′, 239′soldered or attached at terminals 224 a′, 224 b′, or such as viasoldering the ends 236 b′, 237 b′ of the wires directly to the terminalsor busbars at the movable window panel or the like). When attached atterminals 224 a′, 224 b′ of heater element 224′ of movable window panel220′, flexible connector 226′ may extend partially along the lowerregion of movable window panel 220′ from the electrical connections atterminals 224 a′, 224 b′, and the flexible connector 226′ may flex orbend so that the flexible connector reverses direction and is routedback over the connections at terminals 224 a′, 224 b′ and extendstowards the terminals 222 a′, 222 b′ of heater grid 222′ at fixed windowpanel 216′. The ends 236 a′, 237 a′ of wires 236′, 237′ may be connectedto terminals 222 a′, 222 b′ via any suitable electrical connectionmeans, such as via having terminal connectors or elements 236 c′, 237 c′that connect to or receive conductive posts or elements 240′, 241′(FIGS. 36C and 39) established or soldered or attached at terminals 222a′, 222 b′ (so as to provide a solderless connection between theflexible cable and the conductive posts) or the electrical connectionmeans may comprises soldering or otherwise attaching the ends of theflexible wires directly to the terminals or busbars at the fixed windowpanel. Optionally, a cover element 242′ may be provided at the ends 236a′, 237 a′ of the flexible connector or cable 226′ to encase and concealand protect the electrical connections at the terminals 222 a′, 222 b′.Similarly, a cover element 244′ may be provided at the ends of thejumper wire 228′ that connect to the terminals 222 a′, 222 b′ of heatergrid 222′ of fixed window panel 216′ to encase and conceal and protectthe electrical connections at the terminals 222 a′, 222 b′.

As shown in FIGS. 34, 36, 36A-C, 38 and 40, window assembly 210′includes a cover element 246′ that is attached (such as via an adhesive248′ or the like) to and that extends partially along the lower rail orchannel 214 a′ of the frame portion 214′ of window assembly 210′. Thecover element 246′ includes an attaching portion 246 a′ that is attachedto lower rail 214 a′ and includes a wire guide portion or channel 246 b′that is disposed at or above the lower rail 214 a′ and that receivesflexible cable 226′ therein to guide and conceal the flexible cable 226′during movement of the movable window panel between its opened andclosed positions. As can be seen in FIGS. 36B, 40 and 41, an adhesivestrip 250′ (such as an adhesive tape or pressure sensitive adhesive orlayer of adhesive or the like) may be disposed partially along flexiblecable 226′ and may adhere a portion of the flexible cable 226′ to aninner surface of the wire guide portion or channel 246 b′ of coverelement 246′. For example, the portion (such as around half of thelength of the flexible cable) that is towards the ends 236 a′, 237 a′ ofwires 236′, 237′ that connect to the terminals 222 a′, 222 b′ at fixedwindow panel 216′ may be fixedly secured or adhered to the cover elementso that flexing of the flexible element only occurs at the portion ofthe cable that is towards the movable window panel, thereby controllingflexing and folding of the flexible cable as the movable window panel ismoved between its opened and closed positions. Optionally, because theoutboard portion of the cable is substantially fixed relative to theframe and fixed window panel via the adhesive strip or layer, it isenvisioned that other means may be implemented for providing electricalcurrent or power partially along the cover element, such as providing afixed or non-flexible connector or wire or trace partially along thecover element or the rail or the like, with a flexible connectorconnecting to the non-flexible connector at or near a midpoint of thetravel distance of the movable window panel, whereby the flexibleconnector would flex during movement of the movable window panel in asimilar manner as described above.

Thus, the flexible cable 226′ is routed along and within the guideelement or channel 246 b′ to control and guide and conceal the flexiblecable. The flexible cable thus flexes at its non-attached or non-adheredportion (where the cable is not attached/adhered to the cover element246′) as the movable window panel is moved between its opened and closedpositions. The cover element conceals the flexible cable from view andsubstantially encases the flexible cable to guide or control the flexingof the cable and to protect the cable from exposure at the window panel.

Optionally, and with reference to FIGS. 42-49, a rear slider windowassembly 310 includes fixed window panels 316, 318 and a movable windowpanel 320, with heater grids 322, 323, 324 established thereat, such asin a similar manner as discussed above. The heater grids 322, 323, 324and jumper wire or cable 328 of window assembly 310 are substantiallysimilar to the heater grids and jumper wires or cables of windowassemblies 210, 210′, discussed above, such that a detailed discussionof the heater grids and jumper wires need not be repeated herein. Thesimilar or common elements of the heater grids and jumper wires arereferenced in FIGS. 42-49 with similar reference numbers as used inFIGS. 32 and 33, but with 100 added to the reference numbers for FIGS.42-49.

Similar to window assembly 210′, window assembly 310 includes a flexibleconnector 326 that flexes in one direction (to allow the flexibleconnector to fold over itself as the movable window panel is movedbetween its opened and closed positions), while limiting flexing in theother direction (such as in a vertical direction when the windowassembly is normally installed in a vehicle). As shown in FIGS. 44, 45and 49, the ends 336 a, 337 a of the wires 336, 337 of flexibleconnector 326 electrically connect to a connector 338 at movable windowpanel 320, and the ends 336 b, 337 b of the wires 336, 337 of flexibleconnector 326 electrically connect to or receive (via connectors 336 c,337 c) conductive posts or elements 340, 341 established or soldered orattached at terminals 322 a, 322 b at fixed window panel 316, such as ina similar manner as described above with respect to window assembly210′. A cover element 346 is attached to (such as via an adhesive or thelike) and extends partially along the lower rail or channel 314 a of theframe portion 314 of window assembly 310, and the cover element 346includes an attaching portion 346 a that is attached to lower rail 314 aand a wire guide portion or channel 346 b that is disposed above thelower rail 314 a and that receives flexible cable 326 therein to guideand conceal the flexible cable 326 during movement of the movable windowpanel between its opened and closed positions, such as described above.An adhesive strip 350 (such as an adhesive tape or pressure sensitiveadhesive or layer of adhesive or the like) may be disposed partiallyalong flexible cable 326 and may adhere a portion of the flexible cable326 to an inner surface of the wire guide portion or channel 346 b ofcover element 346, such as described above.

In the illustrated embodiment, flexible cable 326 comprises a ribboncable having two electrically conductive wires or traces 336, 337disposed or established along a thin flexible substrate or element 326a. As shown in FIG. 49, the ends 336 a, 337 a of wires 336, 337 may havean electrical connector 339 established thereat or attached or connectedthereto, and the electrical connector 339 may be attachable to orelectrically connected to the busbar terminals 324 a, 324 b of themovable window panel 320. When so connected or attached, the flexiblecable 326 extends from the electrical connections 339 partially alongthe movable window panel 320 and bends or flexes to reverse direction soas to be routed back over the connections 339 and extends towards theterminals 322 a, 322 b of heater grid 322 at fixed window panel 316,such as discussed above.

In the illustrated embodiment, a guide element 352 is provided at themovable window panel 320 and generally at the connector 339, with theguide element 352 extending partially along the flexible cable 326 andtowards the electrical connections at the fixed window panel 316. Theguide element 352 includes an attaching portion 352 a (that attaches toan attachment element 354 at the electrical connector 339) and a guideportion 352 b (that extends from the attaching portion 352 a). The guideportion 352 b has a rounded or curved end portion that is configured tomove along the flexible connector or cable 326 as the movable windowpanel 320 is moved towards its open position to smooth or flattenflexible cable 326 and to limit unwanted flexing or bending of the cablebetween the forward or leading edge of the movable window panel (theedge that is leading in the direction of travel of the movable windowpanel as the movable window panel is moved towards its opened position)and the electrical connection of the flexible cable at the fixed windowpanel 316.

In the illustrated embodiment, the attachment element 354 is disposed atconnector 339 and may be attached at the movable window panel 320 tocover or encompass the connector 339 at busbars 324 a, 324 b. Theattachment element 354 may comprise a socket type connector having aplurality of receiving portions or holes established therein forreceiving a plurality of prongs or terminals protruding from attachingportion 352 a of guide element 352. Thus, guide element 352 may bepressed into and against attachment element 354 to attach guide element352 at the movable window panel 320. Such attachment of the guideelement 352 at the movable window panel 320 may be accomplished afterthe flexible cable is attached at the busbars of the movable windowpanel and before the opposite end of the flexible cable is attached atthe busbars of the fixed window panel, whereby, after attachment of theguide element 352, the flexible cable is flexed or bent or routed backover the guide element and towards the connectors 340, 341 at the fixedwindow panel for connection thereto.

Thus, the guide element 352 provides a means for guiding and smoothingor flattening the flexible cable in front of the movable window panel asthe movable window panel is moved towards its opened position. The guideelement thus may limit or substantially preclude flexing or bending orkinking or wrinkling of the flexible cable in front of the movablewindow panel as the movable window panel is moved towards its openedposition. The guide element is shaped and dimensioned to be wide enoughto substantially or entirely encompass the width of the flexible cable,and the guide element has a rounded forward engaging surface that mayengage or move and slide along the flexible connector or cable and theguide element may function to effect an ironing out of the flexiblecable to reduce or remove wrinkles that may otherwise occur in theflexible cable in front of the movable window panel. The guide elementthus provides a leading structured edge (preferably with a curvaturethereat) that is dimensioned to iron out the flexible cable as themovable window panel is moved towards its opened position.

Thus, the flexible wire or cable functions to provide electricalconnection to the heater grid of the movable window panel throughout therange of motion of the movable window panel between its fully closedposition and its fully opened position. As the window panel is movedtowards its opened position, the one end of the flexible cable moveswith the movable window panel while the flexible cable flexes to allowfor such movement. In the illustrated embodiment, the slider or movablewindow panel is movable towards the driver or left side of the vehiclewhen at least partially opened, but clearly, the slider may be moved inthe other direction, with the components discussed herein reversed,depending on the particular application of the rear slider windowassembly.

Optionally, the electrically conductive connection between the fixedwindow panel or frame and the movable window panel may be establishedand maintained via other suitable means, such as via other types orforms of electrically conductive wiring or cables or via other movablecontacts or the like. Optionally, the electrical contacts may beprovided via other suitable means and may be provided along the upperrail of the window assembly, such as via a flexible wire or ribbon cabledisposed at the upper rail of the window assembly. For example, and withreference to FIGS. 50 and 51, a rear slider window assembly 310′ of avehicle (such as a pickup truck or the like) includes a window frame314′, a pair of side fixed window panels 316′, 318′ and a movable windowpanel 320′ that is movable relative to frame 314′ and fixed windowpanels 316′, 318′ between a closed position (FIG. 50) and an openedposition (FIG. 51). Fixed window panels 316′, 318′ may each include anelectrically conductive heater grid or other heating element orelectrically operable element (not shown in FIGS. 50 and 51) establishedat the window panels (such as at or on an interior surface of the windowpanels) and movable window panel 320′ includes an electrically operatedelement, such as an electrically conductive heater grid (not shown inFIGS. 50 and 51) or other heating element or electrically operableelement, established at the window panel (such as at or on an interiorsurface of the movable window panel).

In the illustrated embodiment, electrical connection between the heatergrid or electrically operable element of the movable window panel 320′and the power source or wiring harness of the vehicle is established viaa flexible electrically conductive wire or ribbon cable 326′ that iselectrically connected at one end 326 a′ to electrically poweredterminals or busbars 322′ at the frame 314′ or fixed window panel 316′,and at the other end 326 b′ to electrically conductive contacts that areelectrically conductively connected to respective traces or busbars ofthe heater grid of the movable window panel 320′. Optionally, the end326 b′ of the flexible cable 326′ may connect to a jumper element (suchas a metallic or polymeric non-flexible element with electricallyconductive traces or elements disposed therealong), which extends fromthe upper rail or frame portion to the surface of the fixed windowpanel, such as at or near the perimeter region of the fixed window paneland where an opaque layer or coating (such as a ceramic frit layer orthe like) may be established at the surface of the fixed window panel.The flexible wire or ribbon cable 326′ flexes and folds over on itselfor overlays itself in a controlled manner (along the upper rail or frameportion 314 b′) as the movable window panel 320′ moves along the frameportion between opened and closed positions, such as in a similar manneras discussed above. The flexible wire or ribbon cable may comprise anysuitable wire or cable, and may comprise a pair of electricallyconductive wires arranged in a generally flat or planar elongated strip,whereby the strip may be flexible in one direction (such as horizontallyor forward and/or rearward in FIGS. 50 and 51 and relative to thevehicle direction of travel), while resisting flexing in otherdirections (such as upward and/or downward in FIGS. 50 and 51), such asin a similar manner as described above.

The electrically powered terminals at the frame 314′ or fixed windowpanel 316′ (to which the ends 326 a′ of wire or cable 326′ areelectrically connected, such as via soldering or the like) areelectrically conductively connected to the power source of the vehicle,such as via electrically conductive connection with a wiring harness ofthe vehicle or a heater grid or the like of the fixed window panel(which in turn is electrically conductively connected to the vehiclewire harness or the like), while the end 326 b′ of electrical wiring orcable 326′ is electrically conductively connected to respective busbarsor traces of the heater grid of movable window panel 320′ (such as viasoldering or the like). Thus, the heater grid of movable window panel320′ is electrically conductively connected to the electricallyconductive terminals 322′ (such as via continuous connection via wire orcable 326′ and via flexing or bending of wire or cable 326′)irrespective of the position of the movable window panel and as themovable window is moved between its closed position and its openedposition.

Optionally, other means for establishing and maintaining electricalconnection to the heater grid of the movable window panel throughout therange of motion of the movable window panel may be implemented whileremaining within the spirit and scope of the present invention. Althoughshown and described as a rear slider window assembly having a pair ofside fixed window panels and a single horizontally movable window panel,other slider window configurations may be implemented while remainingwithin the spirit and scope of the present invention. For example, awindow assembly may have a single fixed window panel with one or moremovable window panels that is/are movable relative to the fixed windowpanel between opened and closed positions while the heater grid of themovable window panel/panels remain electrically conductively connectedto a power source so that the heater grid/grids may be poweredirrespective of whether the movable window/windows is/are opened orclosed. Optionally, it is envisioned that aspects of the presentinvention may be suitable for a vertically movable window panel that hasone or more movable window panels that is/are vertically movablerelative to one or more fixed window panels of the window assembly.

Although shown and described as having a heater grid and providingelectrical power or current to the heater grid to heat or defog ordefrost the movable window panel of the rear slider window assembly, itis envisioned that electrical power/current may be provided to themovable window panel (when the movable window panel is closed and atleast partially opened) for other functions or purposes while remainingwithin the spirit and scope of the present invention. For example,electrical power or electrical current or electrically conductiveconnections may be provided to the movable glass window panel forconnecting to a radio antenna established at the movable window paneland/or carrier of the movable window panel (such as for receiving radioantenna signals or the like), or for powering/controlling lights and/orsensors (such as imaging sensors or photosensors or security/motionsensors or the like) established at the movable window panel and/orcarrier or frame of the movable window panel, or forpowering/controlling an electrical auto-dimming/shading glass panel(such as an electro-optic or electrochromic glass panel or the like) toprovide a dimming/shading feature to the movable glass window panel,and/or the like. The electrical connections or electrically conductiveconnections to the movable window panel allow for provision ofelectrical power/current to the accessories or features or content ofthe movable window panel or at the movable window panel and/or mayprovide a data/signal transmitting/receiving function for theaccessories or features or content of or at the movable window panel,with the connections providing suchpower/current/transmission/communication irrespective of the position ofthe movable window panel between its fully closed position and its fullyopened position.

Thus, and in accordance with the present invention, electricalconductive continuity and hence heating via the electrically conductingheater traces (or other electrically conductive traces or elementsestablished at the movable window panel) is maintained whether or notthe central sliding or movable window panel is opened or closed orpartially opened or partially closed. Thus, a driver of the equippedvehicle can opt to, for example, at least partially open the slidingwindow for ventilation purposes or the like, and still maintain thebenefit of a heatable central sliding window panel for demisting and/ordefogging and/or defrosting purposes. This is in stark contrast toconventional known slider window assemblies, epitomized such as by thelikes of U.S. Pat. No. 6,014,840, which is hereby incorporated herein byreference in its entirety, where electrical connection to the centralsliding window panel (and hence heating/demisting thereof) is lostimmediately when the sliding window is moved from its fully closedposition.

Optionally, and with reference to FIGS. 52-65, a flush rear sliderwindow assembly 410 of a vehicle (such as a pickup truck or the like)includes a frame portion having a lower rail 414 a and an upper rail 414b, a pair of spaced apart fixed window panels 416, 418 and a movablewindow panel assembly 420 that is movable relative to frame and fixedwindow panel or panels between an opened position (where the movablewindow panel assembly is disposed behind and generally along one of thefixed window panels 416) and a closed position (where an outer surfaceof the glass window panel 420 a is generally flush with or coplanar withthe outer surfaces of the fixed window panels 416, 418). The movablewindow panel assembly 420 comprises a glass window panel 420 a that issupported by or bonded to a carrier or frame 420 b (such as bonded tothe frame via a one component urethane adhesive or other suitableadhesive or the like) that includes pins 456 and channel followers 458that are at least partially received in channels 460, 462 formed orestablished along the upper and lower rails 414 a, 414 b of the windowassembly to guide the movable window panel along the upper and lowerrails between its opened and closed positions, as discussed below.

As shown in FIG. 54, the window assembly 410 includes an upper rail 414a bonded along an upper region of the fixed glass panels 416, 418 and alower rail 414 b bonded along a lower region of the fixed glass panels416, 418, with the movable window panel assembly 420 being slidablymovable along the rails 414 a, 414 b via the pins 456 and channelfollowers 458. The rails 414 a, 414 b each include a pair of channels460, 462 (FIGS. 59-63), which comprise a leading channel 460 (whichguides the portion of the movable window panel assembly that leads theassembly as the movable window assembly is moved towards its closedposition) and a trailing channel 462 (which guides the portion of themovable window panel assembly that trails the assembly as the assemblyis moved towards its closed position. As best shown in FIGS. 59-63, eachchannel 460, 462 comprises a generally straight elongated portion 460 a,462 a and a curved end portion 460 b, 462 b at its leading end (the endof the channel closest to the window opening). As also shown in FIGS.59-63, trailing channels 462 comprise narrow grooves formed into rails414 a, 414 b, while leading channels 460 are wider channels (forreceiving a larger channel follower 458 therein, with the rails 414 a,414 b each including a narrower groove or channel 461 establishedgenerally along the center of the leading channel 460 for receiving apin portion 458 a of the channel follower 458 therein, as discussedbelow. Thus, the movable window assembly 420 is moved along theelongated straight portions of the channels towards the window opening,and moved along the curved end portions to move the glass panel into theopening so that the window is closed and the outer surface of the glasspanel is generally flush with or coplanar with the outer surface of thefixed window panels.

A perimeter sealing element 464 is disposed at or adhered or bonded tothe inboard edge regions of the fixed window panels 416, 418 and alongrespective portions 414 c of the lower and upper rails 414 a, 414 b,such that the frame 420 b of the movable window assembly 420 engages andseals against the sealing element 464 when the movable window panel isclosed. Lower and upper appliqués or panels 417 a, 417 b may be adheredor bonded or otherwise attached at the respective rails 414 a, 414 b andbetween the fixed window panels to provide a generally flush outersurface across the fixed window panels and appliqués. Optionally, theappliqués or panels may be integrally molded or formed with therespective rails, such as by utilizing aspects of the window assembliesdescribed above.

Optionally, and with reference to FIGS. 54A and 54B, the movable windowassembly 420′ may have a perimeter seal 464′ attached to or at the frame420 b′, such as via an adhesive bead 464 a′ or the like. As shown inFIG. 54B, the seal 464′ may be disposed outboard of the window panel 420a′ and around the periphery of the window panel, and on a surface of theframe 420 b′ that faces the fixed window panels and/or appliqués whenthe movable window assembly is moved along the rails. The frame 420 b′may be adhered or bonded to the inner surface of the movable windowpanel 420 a′, such as via an adhesive or the like. As can be seen inFIG. 54B, the seal 464′ is spaced from the perimeter edge of the windowpanel 420 a′ so that the seal engages the surfaces of the fixed windowpanels and/or appliqués 414 c′ near the frame portion (such as near thelower frame portion 414 a′ as shown in FIG. 54B) when the movable windowassembly is moved to its closed position. As also can be seen withreference to FIG. 54B, the seal is disposed at a surface of the framethat is behind or rearward of the plane of the window panel 420 a′, suchthat, when the movable window assembly is in its closed position and theseal 464′ is engaged or sealed against the surfaces of the fixed windowpanels and appliqués 414 c′, the window panel 420 a′ is generally in thesame plane as the fixed window panels and appliqués, thereby providinggenerally flush or coplanar outer surfaces of the movable window panel,the fixed window panels and the appliqués.

As shown in FIG. 55, movable window panel assembly 420 includes channelfollowers 458 at the upper and lower leading corners (the portion of themovable window panel assembly that leads the assembly as the assembly ismoved towards its closed position) and channel pins 456 at the upper andlower trailing corners (the portion of the movable window panel assemblythat trails the assembly as the assembly is moved towards its closedposition), with the channel pins disposed at the opposite ends of alatching mechanism 466 that functions to move the detent pins 466 a outof recesses or holes in the channels of the rails to allow for manualmovement of the movable window panel assembly (such as for applicationsof the rear slider window assembly where the movable window panel is notmoved via a powered drive system as discussed below). In the illustratedembodiment, latching mechanism 466 includes detent pins 466 a that aremovably disposed at a latch handle 466 b and detent pin spring 466 c,with the channel pins 456 disposed at the outer ends of the detent pins466 a. The detent pins 466 a are received through holes or openings inthe frame 420 b and are received through the channel pins 456 so thatthe ends of the detent pins 466 a are received through the openings orholes 415 (FIGS. 59-63) in the rails 414 a, 414 b to retain the movablewindow panel at a desired position relative to the fixed panels andwindow opening. The latching mechanism 466 is disposed at the trailingportion of the movable frame 420 b and may be substantially encased orenclosed thereat via a frame cover 420 c.

Thus, the detent pins 466 a are biased outwardly towards the rails so asto be received in corresponding holes 415 formed at the bottom of thechannels to lock or retain the movable window panel assembly at adesired location relative to the fixed window panels and the opening.When a user wants to move the movable window panel assembly, the usermay grasp the handles 466 b and squeeze them together, which imparts aretracting force at the detent pins 466 a to draw the ends of the detentpins 466 a out of the holes and to allow for movement of the movablewindow panel assembly along the rails 414 a, 414 b. Optionally, and asshown in FIG. 56, leaf springs 466 d may be disposed at the handles 466b to bias or urge the latch handles outward to reduce or limit rattle ofthe handles while the window panel is in an open or partially openposition and between detent locking holes. The leaf springs may beattached to the frame cover 420 c, such as mechanically attached viabarbs on the spring that engage the cover. The detent pins thus areguided into the frame through frame holes and are separated and actuatedby the detent pin spring, which is held in place by the latch handles,which may be mechanically attached to the frame 420 b of the movablewindow assembly 420.

In the illustrated embodiment, and such as shown in FIGS. 59-63, theupper and lower trailing channels 462 are formed to at least partiallyreceive the pin followers 456 therein, while the upper and lower leadingchannels 460 are formed to at least partially receive the channelfollowers 458 therein. The pin followers 456 are disposed at the ends ofthe detent pins 466 a and are biased outwardly (such as via springs 457)and towards and into the respective trailing channels 462, while thechannel followers 458 are mounted at the upper and lower leading cornersof the frame 420 b and are also biased outwardly (such as via springs459) and towards and into the respective leading channels 460. Thebiasing of the pin followers and channel followers at all corners of themovable window panel assembly function to float the movable window panel420 a and frame 420 b between the rails 414 a, 414 b, thus centering thewindow module or assembly 420 and reducing chucking movement of thepanel during opening and closing of the movable window panel.

As shown in FIG. 55, the channel followers 458 include a pin portion 458a that extends through the channel 460 and through narrower channel orgroove 461 and into sliding engagement with a bottom region or portionof the respective rail 414 a, 414 b, and a wider lobed portion 458 bthat moves along the respective channel 460 to guide the movable windowpanel between its opened and closed positions. The pin portion 458 a ofchannel follower 458 slidingly engages or contacts the bottom region ofthe rail so that the wider lobed portion 458 b of channel follower 458is spaced from an upper surface of the rail in the channel 460, suchthat only the sides of the channel follower 458 contact the sidewalls ofthe channel as the channel follower is moved along the channel. Suchpin-to-rail contact reduces the frictional contact between the channelfollower and the rail and may provide enhanced movement of the movablewindow panel between its opened and closed positions.

As shown in FIG. 65, the lobe 458 b of the channel follower 458functions to guide the channel follower and movable window along thechannel 460 so as to guide the window into its closed position. When thechannel follower is received in or moved to the curved end portion 460 bof channel 460 (such as shown in FIG. 65), the lobed channel follower458 may also provide an “anti-theft” function by limiting movement ofthe movable window if the window is pushed on from outside of thevehicle. For example, when the window is closed, the channel followersare driven in towards the fixed glass and provide a means of securingthe non-latched portion of the movable window from forced entry fromoutside of the vehicle.

Optionally, and as shown in FIG. 64, the rails 414 a, 414 b may includea notch or groove 414 d at a corresponding portion of each channel (orof a set of channels, such as at each leading channel or the like) thatallows for insertion of the channel follower or pin follower to easeinstallation or loading of the movable window panel onto the rails.After the movable window panel is loaded onto or into the rails, a railcover 414 e may be pushed into the notch or groove and may snap in placeat the rail to limit or substantially preclude the movable window panelfrom being dislodged from the rails.

For example, and with reference to FIGS. 64A-D, the movable window panelassembly 420 may be angled relative to the channels or rails 414 a, 414b so that first a lower channel follower 458 may be inserted into thechannel of lower rail 414 a (such as shown in FIG. 64A), and then themovable window panel assembly 420 may be pivoted to align the upperchannel follower 458 with the channel of the upper rail 414 b and thenfurther pivoted so that the upper channel receives or partially receivesthe upper channel follower 458 therein (such as shown in FIG. 64B). Asshown in FIG. 64B, this is done while the pin followers and pins 456 arepivoted away from the rails 414 a, 414 b. After the channel followers458 are received in their respective channels, the movable window panelassembly 420 may be moved along the rails and pivoted to position thepin followers 456 generally at the slots or grooves 414 d at the upperand lower rails 414 b, 414 a (such as shown in FIG. 64B). The movablewindow panel assembly 420 may then be pivoted to move the pin followers456 through the grooves 414 d and into the respective channels of therails 414 a, 414 b (such as shown in FIG. 64C) and, after the movablewindow panel is so loaded onto or into the rails, the rail covers 414 emay be pushed into the grooves 414 d and may be snapped in place orotherwise retained at the rails 414 a, 414 b (such as shown in FIG. 64D)to limit or substantially preclude the movable window panel from beingdislodged from the rails. Although shown in FIGS. 64A-D as a windowassembly having a hole in a fixed window panel and a movable windowpanel assembly that moves relative to the single fixed window panel,clearly, the installation method and means shown in FIGS. 64A-D areapplicable to any flush rear slider window assembly (such as a rearslider window assembly having a single fixed panel or dual fixed panelsor the like, such as discussed herein) or flush side slider windowassembly (such as the types described above) or the like, whileremaining within the spirit and scope of the present invention.

Optionally, and as shown in FIGS. 66-74, the rear slider window assembly410′ may comprise a powered heater slider window assembly with a cabledrive system operable to move the movable window panel between itsopened and closed positions, as discussed below. Because rear sliderwindow assembly 410′ is otherwise substantially similar to rear sliderwindow assembly 410, discussed above, the same reference numbers areused for the similar or common components of the window assemblies. Asshown in FIGS. 66, 67 and 72-74, rear slider window assembly 410′includes heater grids at one or more of the window panels. For example,the fixed window panels 416, 418 may include heater grids 422, 423,while the movable window panel 420 a may include a heater grid 424. Theheater grids may include terminals for connection to a vehicle powersource and busbars and/or a jumper wire or the like, such as describedabove. Because the movable window panel is guided along curved tracks orchannels and is moved from a plane rearward of and along the fixedwindow panel or panels to a plane that is generally coplanar with thefixed window panels, the flexible connectors described above may not besuitable to provide power to the heater grid of the movable windowpanel. Thus, optionally, and desirably, the rear slider window assembly410′ may include a flexible electrical connector 468 for establishingelectrical connection between the heater grid 422 of fixed window panel416 and the heater grid 424 of movable window panel 420 a by extendingthrough one of the pins or channel followers of the movable window panelassembly 420. In the illustrated embodiment, a portion of the flexibleconnector 468 is disposed partially along the upper rail 414 b and alongor adjacent to the upper trailing channel 462, and another portion ofthe flexible connector is routed down and through the upper pin orchannel follower 458 to connect to the heater grid of the movable windowpanel 420 a.

As can be seen with reference to FIGS. 75A and 75B, flexible connector468 comprises a flexible flat cable or ribbon cable 470 at one endportion and a pair of wires 472 at the other end portion, with theribbon cable 470 electrically connecting to the pair of wires 472 at aguide element 474 (and with the wiring connected at the guide elementvia any suitable means and optionally, with the guide element comprisinga plastic or polymeric element that has electrical conductors insertmolded therein to provide electrical connection between the ribbon cable470 and the pair of wires 472). A fixed end 470 a of ribbon cable 470 offlexible connector 468 includes a pair of terminals 470 b, which areattached at respective terminals at fixed window panel 416, while aconnecting end 472 a of wires 472 includes a pair of terminals 472 b,which are attached at respective terminals of heater grid 424 of movablewindow panel 420 a. The terminals 470 b, 472 b may be covered or housedby a plastic or polymeric overmold 470 c, 472 c, to conceal theelectrical connections at the respective heater grids or terminals. Theterminals 470 b, 472 b may be snapped or otherwise secured to therespective terminals at the window panels, which may be soldered orotherwise electrically conductively attached or connected to the busbarsat the window panels, such as in a similar manner as discussed above.

As best shown in FIGS. 68 and 68A, flexible ribbon cable 470 is disposedalong upper rail 414 a and along a channel or recess 414 e establishedbetween the walls of upper trailing channel 462 and a mounting portion414 f of upper rail 414 a. The guide element 474 moves along a groove462 c established through channel 462 and includes a first connectingportion 474 a that connects to the ribbon cable 470 and an upper portion474 b that rides or slides along the rail 414 a and a pin portion orsecond connecting portion 474 c that protrudes through groove 462 c,with the upper portion 474 b joining or bridging between connectingportions 474 a, 474 c, and with electrically conductive elementsextending through the connecting portions and upper portion toelectrically conductively connect the wires or electrically conductingelements of ribbon cable 470 with the wires 472 at the movable windowpanel. As best shown in FIG. 68B, the wires 472 extend through thechannel follower or pin at the upper trailing corner of the movablewindow assembly 420. Note that, because rear slider window assembly 410′is a powered slider window, a channel follower 458 is disposed at theupper trailing corner of the movable window assembly 420, but the wiresmay be routed through a pin 456 and partially along or around the detentpin 466 a for applications of the heater grid powering system with amanually movable rear slider window assembly such as rear slider windowassembly 410, discussed above.

Thus, the guide element 474 is moved along the channel 462 as themovable window panel is moved between its opened and closed positions.The flexible ribbon cable 470 flexes and folds over itself as themovable window is opened (such as in a similar manner as the flexiblecables described above, and optionally with similar guiding means andattaching means as discussed above), while the wires 472 make theelectrical connection from the guide element 474 to the terminals at themovable window panel. The wires 472 extend through the pin or channelfollower 458 and through the frame 420 b and to the glass surface of thewindow panel at or near the upper trailing corner of the window panel420 a. The frame 420 b may be modified or configured encase or house orcover the overmold or cover 472 c at the attachment of the wires 472 tothe terminals at the movable window panel 420 a. The flexible connector468 thus establishes electrically conductive connection between theelectrical terminals at the fixed window panel (or optionally at theframe or other fixed portion of the window assembly or vehicle) and theelectrical terminals at the movable window panel to provide electricalpower to the heater grid of the movable window panel irrespective of aposition of the movable window panel relative to the fixed window panelsof the flush rear slider window assembly.

Optionally, any of the rear slider window assembly exemplary embodimentsof the present invention discussed above may comprise a single fixedwindow panel with a hole or opening established therethrough and withthe rails bonded to or disposed along the single panel to provide formovement of the movable window panel relative to the single fixed panelto open and close the window opening. For example, and with reference toFIGS. 76-78, a rear slider window assembly 510 includes a single fixedwindow panel 516 and a movable window panel assembly 520 that is movablealong rails 514 a, 514 b adhered or bonded or attached to the fixedwindow panel 516, such as in a similar manner as described above. In theillustrated embodiment, the rear slider window assembly 510 comprises aflush rear slider window assembly similar to rear slider windowassemblies 410, 410′, discussed above. Because many of the elements andaspects of the rear slider window assembly 510 are similar to rearslider window assemblies 410, 410′, a detailed discussion of the windowassemblies need not be repeated herein. The common or substantiallysimilar components or elements of the window assemblies are referencedwith like reference numbers, but with 100 added to the reference numbersin FIGS. 76-79.

As shown in FIGS. 77A-C, the lower frame 514 a is bonded to the fixedwindow panel 516 generally below the opening 516 a established throughfixed window panel 516, with the perimeter sealing element 564 bonded oradhered to the fixed panel 516 around the opening 516 a, such that theframe 520 b of the movable window assembly 520 engages the seal 564 whenthe movable window panel is moved to its closed position, with themovable panel 520 a being disposed in the opening 516 a and generallycoplanar with the fixed window panel 516. Optionally, and with referenceto FIG. 77D, for window assembly 410′, discussed above, the lower rail414 a may be bonded to the appliqué 417 a, with the rail including theportion at which the sealing element 464 is disposed.

In the illustrated embodiment, rear slider window assembly 510 comprisesa powered slider window assembly, with a powered cable drive system 580operable to open and close the movable window assembly 520 between itsopened and closed positions. Because the movable window assembly 520 ofrear slider window assembly 510 is moved via a cable drive system, thedetent springs and latching mechanism are not incorporated into themovable window assembly 520, and instead, and as shown in FIG. 79,movable window assembly 520 includes three channel followers 558, 558′disposed at the upper and lower leading corners of the frame 520 b andat the upper trailing corner of the frame 520 b (where a flexible heatergrid wiring assembly 568 may be disposed to provide electrical power toa heater grid at the movable window panel 520 a, such as in a similarmanner as described above).

The drive assembly or system 580 may comprise a cable 582 that isattached at a connector at or near one of the pins or channel followersof the movable window panel, whereby movement of the cable or cables ineither direction causes movement of the movable window panel between itsopened and closed positions. For example, and as can be seen withreference to FIGS. 78-83, the cable 582 may attach or connect at a lowerfollowing or trailing pin 556 of the movable window panel (that followsor trails the lower leading pin as the movable window panel is movedtowards its closed position), and a link 584 may be connected betweenthe following or trailing pin 556 and the leading pin and/or channelfollower 558′. The link 584 functions to exert a pushing or pullingforce at the leading pin and/or channel follower 558′ as the movablewindow assembly 520 is moved between its opened and closed positions,and may be connected at the leading channel follower 558′ at a slot 558c established at least partially along and at least partially throughthe lobe 558 b of the leading channel follower 558′.

In the illustrated embodiment, pin 556 includes a lobe or tab 556 a thathas an aperture or hole for receiving or connecting to an end of link584. A cable connector 586 is attached at an outer portion of the tab556 a and is connected to cable 582, such as via fixedly attaching toopposed ends of the cable or otherwise fixedly attaching to the cablesuch that movement of the cable or cables along rail 514 a imparts acorresponding movement of the cable connector 586 and pin 556 andmovable window assembly 520. Link 584 extends from pin 556 and generallyalong the lower rail 514 a and is received in the slot 558 c of the lobeor tab 558 b of the channel follower 558′.

As can be seen with reference to FIGS. 79-81 and 54A-C, link 584 extendsalong rail 514 a above the lower channels 560, 562 (where the pins andchannel followers and link and rails may be covered or encased bysuitable trim or cover elements to conceal the moving parts of the rearslider window assembly in a known manner). As shown in FIGS. 84A-C,lower rail 514 a includes a cable routing channel 588 establishedgenerally along the rail and generally parallel to the elongatedstraight portion 562 a of lower channel 562. The cable 582 and cableconnector 586 move along the channel 588 pulling the window assembly ineither direction responsive to the drive motor 580 a of the cable drivesystem 580. As shown in FIG. 84C, the cable conduit 582 a may be securedat opposite ends of the channel 588 and/or rail 514 a, such as via abushing and end cap 582 b fitted into a recessed area at the ends of therail 514 a, which retains the cable so as to maintain the cable in asubstantially straight line throughout the motion of opening or closingof the movable window panel.

Thus, responsive to actuation of the drive motor 580 a, the cable 582pulls at the cable connector 586 in one direction or the other to movethe cable connector 586 and pin 556 along the channel 562. When pin 556is moved via pulling of the cable to close the movable window panel 520a, pin 556 may pivot and move and push link 584 along slot 558 c ofchannel follower 558′, whereby link 584 pushes against channel follower558′ to assist in smoothly moving the movable window assembly 520 alongthe channels and rails to its closed position. When the cable drivemotor is actuated to open the window, the cable 582 pulls at cableconnector 586 and pin 556 in the opposite direction, whereby pin 556 mayrotate and move to open the window, and whereby link 584 may move backalong slot 558 c of channel follower 558′ and pull at an outer portionof the lobe 558 b to retract the channel follower 558′ from the curvedend 560 b of leading channel 560. The slot configuration thus allows forsome pivotal movement of pin 556 when the cable is moved in eitherdirection and may assist in retracting the channel follower from itslocked position at the curved end 560 b of the channel 560 to enhancethe opening of the movable window panel. Thus, the powered rear sliderwindow assembly 510 provides enhanced control of the opening and closingof a flush movable window panel relative to the rails and fixed windowpanel or panels.

Thus, the rear slider window assembly for a vehicle may include a frameportion having an upper rail and a lower rail, a fixed window panel thatis fixed relative to the frame portion, and a movable window panel thatis movable along the upper and lower rails, wherein the movable windowpanel is movable between a closed position and an opened position. Theupper and lower rails comprise channels and the movable window panelcomprises pins and channel followers to track and guide the movablewindow panel along the upper and lower rails between the closed positionand the opened position, and, when closed, the movable window panel isgenerally flush or coplanar with the fixed window panel. The movablewindow panel is movable between the closed position and the openedposition via a powered cable drive system, which comprises at least onecable attached to a connector at a pin of the movable window panel,whereby movement of the at least one cable in either direction moves themovable window panel between the closed position and the openedposition. The pin is disposed at a lower region of the movable windowpanel and is linked to the channel follower at the lower region of themovable window panel via a linkage connected to the pin and to thechannel follower. Optionally, the linkage may be received in a slotestablished partially along a tab of the channel follower and thelinkage may push at the channel follower at one end of the slot when thepowered cable drive system operates to close the movable window paneland the linkage may pull at the channel follower at the other end of theslot when the powered cable drive system operates to open the movablewindow panel.

Optionally, the window assembly may include means for establishing andmaintaining electrical connection to a heater grid of the movable windowpanel throughout the range of motion of the movable window panel may beimplemented while remaining within the spirit and scope of the presentinvention, such as discussed above. The electrical connection means maycomprise a flexible cable that is routed along one of the rails, such asan upper rail, and is routed along and/or through one of the guide pinsand channel followers to the electrical connection at the movable windowpanel, such as also discussed above.

Optionally, the heater grid layouts or configurations for the windowpanels of the rear slider window assemblies of the present invention maycomprise any suitable configuration or routings. As discussed above, theheater grids may be configured to have one or two generally verticalbusbars along one side of the panel and two generally vertical busbarsalong the opposite side to enhance current flow through and along theheater grids. Optionally, it is envisioned that other heater gridconfigurations may be implemented while remaining within the spirit andscope of the present invention.

For example, and with reference to FIGS. 85-87, a rear slider windowassembly 610 may comprise a single fixed window panel 616 with anopening or hole 616 a established therethrough and a movable windowpanel 620 that is movable relative to the fixed window panel betweenopened and closed positions, such as in a similar manner as describedabove. Note that the window assembly of FIGS. 85-87 is shown without therails and without the movable window assembly frame and othercomponents, in order to clearly show the window panels 616, 620 andtheir respective electrically conductive heater grids. The windowassembly may comprise a flush window assembly similar to window assembly510, discussed above, or may comprise a non-flush window assembly, whileremaining within the spirit and scope of the present invention. Also,the window assembly may comprise a powered drive window assembly or amanually opening/closing window assembly, while remaining within thespirit and scope of the present invention.

In the illustrated embodiment, fixed window panel 616 includes a heatergrid 622 having vertically oriented traces 622 a at opposite sides ofthe panel, while movable window panel 620 includes a heater grid 624having vertically oriented traces 624 a. Fixed window panel 616 includesa lower busbar 622 b extending across the fixed panel and electricallyconductively connecting to the lower ends of the vertical traces 622 aat either side region of the fixed window panel, and fixed window panel616 further includes an upper busbar 622 c extending across the fixedpanel and electrically conductively connecting to the upper ends of thevertical traces 622 a at either side region of the fixed window panel.One of the busbars 622 b, 622 c may extend along an outer perimeterregion of the fixed panel 616 so as to provide a connecting region wherea vehicle wiring harness may connect to both busbars at a common area(such as at a corner of the window assembly). For example, and as in theillustrated embodiment, a portion 622 d of the lower busbar 622 bextends along a side perimeter region of the fixed panel and is disposedpartially along and adjacent to (yet spaced from and electricallyisolated from) upper busbar 622 c to establish a connecting region 623for electrically connecting the busbars to a vehicle wiring harness orthe like, such as via any suitable manner.

Similarly, the movable window panel 620 includes a lower busbar 624 bextending across the movable panel and electrically conductivelyconnecting to the lower ends of the vertical traces 624 a and furtherincludes an upper busbar 624 c extending across the movable panel andelectrically conductively connecting to the upper ends of the verticaltraces 624 a. One of the busbars 624 b, 624 c may extend along an outerperimeter region of the movable panel 620 so as to provide a connectingregion where a flexible connector or cable may connect to both busbarsat a common area (such as at a corner of the movable window panel). Forexample, and as in the illustrated embodiment, a portion 624 d of thelower busbar 624 b extends along a side perimeter region of the movablepanel and is disposed partially along and adjacent to (yet spaced fromor electrically isolated from) upper busbar 624 c to establish aconnecting region 625 for electrically connecting the busbars to theflexible connector, such as described above. In the illustratedembodiment, the window assembly comprises a flush movable window panelthat is generally flush with the fixed panel when closed, but aspects ofthe heater grid configuration are suitable for non-flush windowassemblies such as also described above, where a flexible ribbon cableor the like may provide electrical power to a corner region of themovable window panel.

Optionally, and with reference to FIG. 88, a rear slider window assembly610′ may comprise a single fixed window panel 616′ with an opening orhole established therethrough and a movable window panel 620′ that ismovable relative to the fixed window panel between opened and closedpositions, such as in a similar manner as described above, withhorizontal heater grids, as discussed below. Note that the windowassembly of FIG. 88 is shown without the rails and without the movablewindow assembly frame and other components, in order to clearly show thewindow panels 616′, 620′ and their respective electrically conductiveheater grids. The window assembly may comprise a flush window assemblysimilar to window assembly 510′, discussed above, or may comprise anon-flush window assembly, while remaining within the spirit and scopeof the present invention. Also, the window assembly may comprise apowered drive window assembly or a manually opening/closing windowassembly, while remaining within the spirit and scope of the presentinvention.

In the illustrated embodiment, fixed window panel 616′ includes a heatergrid 622′ having horizontally oriented traces 622 a′ at opposite sidesof the panel, while movable window panel 620′ includes a heater grid624′ having horizontally oriented traces 624 a′. Fixed window panel 616′includes a first upper busbar 622 b′ extending across the fixed paneland electrically conductively connecting to the upper ends of sidebusbars 622 d′ (or unitarily formed or established with the side busbars622 d′) at either side/end region of the fixed window panel, and fixedwindow panel 616′ further includes a second upper busbar 622 c′extending across the fixed panel and electrically conductivelyconnecting to the upper ends of side busbars 622 e′ at either side/endregion of the fixed window panel. The busbars 622 b′, 622 c′ provide aconnecting region 622 f′ where a vehicle wiring harness may connect toboth busbars at a common area (such as at a generally central region ofthe window assembly or at a corner region or the like), such as via anysuitable manner. For example, a positive terminal may be provided atupper busbar 622 c′ and a negative terminal may be provided at upperbusbar 622 b′, such as shown in FIG. 88. The fixed window panel 616′further includes vertical busbars 622 g′ along or near the opening, suchthat some of the horizontal heater traces 624 a′ are electricallyconnected between side busbar 622 e′ and busbar 622 g′ and others of thehorizontal heater traces 624 a′ are electrically connected betweenbusbar 622 g′ and side busbar 622 d′.

Similarly, the movable window panel 620′ includes a side busbar 624 b′extending generally vertically along one side region of the movablepanel and electrically conductively connecting to the respective ends ofthe horizontal traces 624 a′ and further includes a second busbar 624 c′extending generally vertically along the opposite side region of themovable panel and electrically conductively connecting to the respectiveends of some of the vertical traces 624 a′, and a third busbar 624 d′that extends generally vertically and partially along the opposite sideregion of the movable panel and electrically conductively connecting tothe respective ends of the others of the vertical traces 624 a′. Thebusbars 624 c′, 624 d′ provide a connecting region 624 e′ where aflexible connector or cable may connect to both busbars at a common area(such as at a corner of the movable window panel), such as in themanners described above. Thus, electrical current may flow along some ofthe horizontal traces 624 a′ between busbars 624 c′ and 624 b′ andelectrical current may flow along others of the horizontal traces 624 a′between busbars 624 b′ and 624 d′. In the illustrated embodiment, thewindow assembly comprises a flush movable window panel that is generallyflush with the fixed panel when closed, but aspects of the heater gridconfiguration are suitable for non-flush window assemblies such as alsodescribed above, where a flexible ribbon cable or the like may provideelectrical power to a corner region of the movable window panel.

Thus, by establishing the busbars across the upper and lower regions ofthe single fixed panel, the window assembly of the present inventionobviates the need for a jumper wire or additional vehicle wiringconnectors or the like, and provides enhanced current flow and heatingat both side regions of the fixed window panel. The busbars may beestablished at or along the surface of the glass panels and a concealinglayer, such as an opaque or substantially opaque frit layer 690, 690′may be disposed at the perimeter regions of the fixed and movable glasspanels to substantially hide or conceal the busbars from view to aperson viewing the window assembly when the window assembly is normallymounted in the vehicle. Although shown as having the vehicle connectionat an upper corner of the fixed window panel (in FIGS. 85-87) or at anupper, generally central location (FIG. 88), clearly the electricalconnection area may be anywhere around the perimeter region of thewindow assembly, such as at another corner than shown, or such as at aside region (where the upper busbar may be disposed partially downwardalong the side region and the lower busbar may be disposed partiallyupward along the side region) or at two separate regions (such as wherea vehicle positive feed connects to either the upper or lower busbar atan upper or lower portion of the window and a vehicle negative feedconnects to either the lower or upper busbar at a lower or upper portionof the window), while remaining within the spirit and scope of thepresent invention. Thus, the window assembly of the present invention(with the conductive busbars extending across the upper and lowerregions of the fixed panel) provides enhanced flexibility forelectrically connecting the heater grid to the vehicle wiring harness,since various connecting locations may be used depending on theparticular application of the window assembly and the desired wiring ofthe vehicle at which the window assembly is installed.

Changes and modifications to the specifically described embodiments maybe carried out without departing from the principles of the presentinvention, which is intended to be limited only by the scope of theappended claims, as interpreted according to the principles of patentlaw.
